Blue, red, green, reset, purple
Public route notes commonly start with the blue lever in the North East Maze, continue through red and green lever states, then use purple and additional red/green toggles before the UFO Key appears.

Quick Route Checklist
Check these points before grinding
Current public guides point to a sewer maze puzzle with colored levers. Treat the order below as a working checklist, then confirm it in game before relying on it after a patch.
| Step | What to inspect | Why it matters |
|---|---|---|
| 1 | Confirm rebirth and sewer access | The community wiki notes rebirth as part of the sewer/UFO route, so check this before grinding the maze. |
| 2 | Follow the lever sequence | Public sources describe the UFO path through blue, red, green, purple, and reset lever states. |
| 3 | Grab the UFO Key in the North East Maze | The UFO key is reported as the hidden item that opens the alien route. |
| 4 | Deliver the key to the alien | Games.gg reports the reward path leads to Joe the Alien and a permanent investor-related bonus. |
| 5 | Save owned screenshot evidence | Original screenshots make the page stronger than copied code-list content. |

Lever route
Public UFO key lever checklist
The route below combines the community wiki and several current guide pages. Use it as a quick checklist, not as a permanent fact: Roblox simulator updates can move maze logic.
Alien route and investor bonus
Multiple guides describe the key as a path to an alien interaction. When you verify the route, capture the exact reward text so this page can replace source notes with owned proof.
Page advantage
How this page can beat thin results
A generic article only says where a key is. A better guide gives route order, prompt screenshots, common wrong turns, and the exact update date. Add your first gameplay captures here before expanding into more Roblox games.
- Capture the UFO gate prompt before opening other tabs.
- Capture sewer entrance prompts and label them as tested or untested.
- Keep outdated route notes visible but marked as old after updates.
